Soil Moisture Hygrometer Detection Module

Soil Moisture Hygrometer Detection Humidity Sensor Module For arduino Development Board ,DIY Robot and Smart Car

Product instruction

• High-quality soil sensors for soil moisture detection, nickel- plated surfacetreatment,widening the induction area, can improve the conductivity, preventcontact with soil easy to rust,prolong service life
• The product can control soil moisture in a wide range, and control the corresponding threshold through potentiometer regulation. When the humidityis lower than the set value, Do output high level, and when the humidity ishigher than the set value, DO output low level
• Comparator uses LM393 chip and works stably
• Working voltage 3.3V-5V
• Fixed bolt hole for easy installation
• PCB size: 3.1cm * 1.43cm

Module usage instructions

• sensors are suitable for soil moisture detection.
• Use the blue potentiometer on the module to adjust the threshold value of soil moisture. Turning it clockwise increases the humidity threshold, while turning it counterclockwise decreases it.
• Digital output DO can be directly connected with single-chip computer,which can detect the high and low levels of soil moisture.
• Connect the output AO of the small board analog to the AD module to obtain more precise values of soil moisture through AD conversion.

Product applications

You can adjust the threshold of soil moisture control using the potentiometer. This adjustment enables automatic control of various applications such as vegetable gardens, garden watering systems, soil moisture levels in family flowerpots, as well as in electronic competitions, electronic building blocks, Arduino designs, and more.
